Forum OpenACS Q&A: Re: Error adding new users to translation server

The site is very slow, so I thought I would install developer support to diagnose it.  However, when I try to install software, or do anything that uses list-builder, I get:

There was a server error processing your request. We apologize.

Here is a detailed dump of what took place at the time of the error, which may assist a programmer in tracking down the problem:

can't read "list_properties(bulk_action_method)": no such element in array
    while executing
"lang::util::localize $list_properties(bulk_action_method)"
    invoked from within
"if {! ([template::util::is_nil list_properties(bulk_actions)])} {

Any tips on debugging?  Could this be related to message keys?  To a botched upgrade?

bulk_action_method was something I added so bulk actions could be POSTs instead of GETs. I am not sure how you could get part of that change an not all of it since I think it was all in acs-templating. Here was the commit that added this.
